Method HasPrefixFold

string.go:744–764

HasPrefixFold succeeds if string has given Go string as prefix after applying Unicode case-folding (so it's a case-insensitive match). Example: str := NewString(t, "Hello World") str.HasPrefixFold("hello")

(value string)

//	str := NewString(t, "Hello World")
//	str.HasPrefixFold("hello")
func (s *String) HasPrefixFold(value string) *String {
	opChain := s.chain.enter("HasPrefixFold()")
	defer opChain.leave()

	if opChain.failed() {
		return s
	}

	if !strings.HasPrefix(strings.ToLower(s.value), strings.ToLower(value)) {
		opChain.fail(AssertionFailure{
			Type:     AssertContainsSubset,
			Actual:   &AssertionValue{s.value},
			Expected: &AssertionValue{value},
			Errors: []error{
				errors.New("expected: string has prefix (if folded)"),
			},
		})
	}

	return s
}

// NotHasPrefixFold succeeds if string doesn't have given Go string as prefix
// after applying Unicode case-folding (so it's a case-insensitive match).
